IMPLEMENT FOR DISMANTLING BUILDERS STAGINGS, SLC.

SPECIFICATION forming part of Letters Patent No. 494,417, dated March28, 1893.

Application led September 27, 1892. Serial No. 447,030. (No model.)

To all whom it may concern:

Beit known that I, GEORGE H. CUTTING, a citizen of the United States,residing at Worcester, in the county of Worcester and State ofMassachusetts, have invented a new and useful Implement for DismantlingBuilders Stagings and Similar Usages, of which the following, togetherwith the accompanying drawings, is a specification sufficiently full,clear, and exact to enable persons skilled in the art to which thisinvention appertains to make and use the same. f

The objects of my present invention are to provide a convenient andefficient implement for use in dismantling or taking down buildersstagings, and by means of which the ledger boards nailed to stagingpoles can be quickly and easily released therefrom without materialinjury to the staging stock; also avoiding the expenditure of time andlabor involved in the usual practice of cutting off the nails at eachpoint of attachment. These objects I attain by the implement illustratedin the drawings, wherein l Figure 1 is a perspective view showing myimplement in position of use. Fig. 2 is a top view of the same, and Fig.3 is a horizontal section showing the offset ends of the pressoff bars.

My invention consists in a tool or implement composed of a pair oflevers having one end offset laterally for taking 'a hold on the angleof the staging-post or upright; also a straight portion adapted to bepressed against the ledger-board near its point of attachment, oradjacent to the sides of the post to which the ledger-board is nailed;and having combined with the other end ahand-lever or means for applyingpower to force the said levers or bars outward, or for crowding theledgerboard and staging post in opposite directions and therebywithdrawing the nails and releasing the attachment of the ledger to thepost.

Referring to parts, A denotes the stagingpole or upright post; B theledger-board fastened thereto by nails n in the usual manner.

C C indicate the press-off-bars or levers of suitable length to reachsomewhat above and below the ledger-board and fitted with the straightportion 2 for resting against the side of the same. The upper ends ofsaid pressoff bar are extended forward and fitted with an eye, as at e,and the parts are connected or pivoted together by a transverselydisposed bolt or pin D, over which the eyes e fit loosely and areretained by nuts or heads d, while their lower ends are oppositelyoffset or provided each with a lateral claw, as at 5, that can hold orserve as a fulcrum on the angle of the post A, as indicated.

A hand-lever or power-applying device F is connected with or fulcrumedon the bolt D said lever having an end or cam 6 that is suitably formedto take bearing against the face of the post A, and exert a force forseparating the parts when the operator swings up the handle end 7 ofsaid lever. This operating device is preferably a lever having a hub 4fixed to the central part or pin D, and fitted with a turned up orcurved end 6 that can roll against the surface of the post. The bolt orfulcrum-pin D is of sufficient length to reach across the face of thestaging-post A and allow the bars C to lie parallel and adjacent to thesides thereof. Said bars C are arranged to slide on the bolt so thatthey can be adjusted inward or outward thereon to any degree that willaccommodate the variations in the size of the staging posts, which mayvaryin size from three inches to four and onehalf inches, more or less.

The operation is as followsz-For releasing the ledger-board the operatordrops the bars C back of the ledger-board B, rests the cam 6 against theface of the post A, adjusts the claws or oiisets 5 to the angles of theposts and then swings up the handle 7. In the compound lever action thecam 6 forces the eye end of the bars C outward and the straight parts 2acting from 5 as a fulcrum press off from the post by a simple, easy andquick movement, and in a manner that will not split the ledger-board ordestroy the staging stud;

thus making a great savingin time, labor and material in the taking downof stagings.

It is obvious that the implement can be made either with the end 6 ofthe hand-lever IOO two press-off bars each having an opposite lateraloffset or claw at one end, cent-rally an edge or bearing surface forengagement With the ledger-board, and a hinging eye at the other end, incombination with a transverse connecting-pivot or holt arranged throughthe said eyes, and a power-applying device connected with said pivot andadapted for action against the post or timber for forcing outward theends of said press-oEE-levers, as set forth.

2. A tool or implement consisting of the press-olic bars or levershaving` the lateral claw or offset at one end and the pivot eye at theGEORGE H. CUTTING.
